Objective To establish the rehabilitation program of external diaphragm pacer and to explore its preventive effect on ventilator-induced diaphragmatic dysfunction（VIDD） in patients with ICU non-invasive mechanical ventilation. Methods Through the literature review,group meeting and pre-experiment,a program was formulated to prevent VIDD in patients with non-invasive ventilation in ICU. Patients with non-invasive ventilation were conveniently selected from September 2020 to June 2021 in a respiratory intensive care unit of a tertiary hospital in Henan province. They were divided into 2 groups by random number table method. On the basis of routine nursing care,the experimental group was given the external diaphragm pacer training program,and the control group was given routine nursing program. The incidence of VIDD,diaphragm thickness score,diaphragm displacement and blood gas analysis were compared between 2 groups after the intervention. Results A total of 74 patients were included with 10 cases fallen off,and finally 64 cases were included with 32 cases in the experimental group and 32 cases in the control group. After the intervention,the incidence of VIDD was 6.25% in the experimental group,while that was 43.75% in the control group. The difference between 2 groups was statistically significant（P=0.001）. Conclusion The external diaphragm pacer rehabilitation program can reduce the incidence of VIDD and improve diaphragm and respiratory function in patients with ICU non-invasive mechanical ventilation.

Objective To translate and revise the Quality of Oncology Nursing Care Scale（QONCS） into Chinese,then to assess the reliability and validity of the Chinese version of the Quality of Oncology Nursing Care Scale（C-QONCS）.Methods Standard forward-back translation techniques were used in the translation of the QONCS according to the Brislin translation model. Cross-cultural revision of the translated QONCS was carried out through group discussion and pilot test. Totally 612 patients with advanced cancer were recruited and investigated using general information questionnaire and the C-QONCS by convenient sampling,and its reliability and validity were assessed.Results The C-QONCS had 5 dimensions：being supported and confirmed（16 items）,spiritual caring（6 items）,sense of belonging（5 items）,being valued（4 items）,being respected（3 items）. The Cronbach’s a coefficient for the overall scale was 0.946,and ranging from 0.735 to 0.928 for each domain. Split-half reliability was 0.879 for the overall scale,and 0.683~0.864 for each domain. Test-retest reliability was 0.867 for the overall scale,and 0.837~0.889 for each domain. Analysis of content validity of the C-QONCS indicated that I-CVl was at least 0.86,S-CVl was 0.97.Conclusion The reliability and validity of C-QONCS are satisfactory and well meet the requirements of psychological measurement,indicating C-QONCS is a reliable and valid instrument in the context of Chinese culture,and can be used to assess the quality of oncology nursing care.
